Shredder's Hideout is the former headquarters of the Foot Clan, located in a decrepit old building with an in-door water tank. This is where he hatches all of his most horrible plots to kill the Turtles. After the events of Triceraton invasion and the destruction of the Heart of Darkness, it was deserted by the foot. It's now under the control of Karai and Shinigami as they both intend to rebuild the Foot and restore the honor that Shredder poisoned with his burning thirst for vengeance.
